ELECTRIC FAN.

SPECIFICATION forming part of Letters Patent No. 483,545, dated October4, 1892.

Application filed May 22, 1891. Serial No. 393,688. (No model.)

To all whom it may concern.-

Be it known that I, ELIsHA B. OUTTEN, residing in the city, county, andState of New 'York, have invented certain new and useful Improvements inElectric Fans, of which the following is a specification.

This invention relates to electrically-driven fans, or those driven byelectro-motors, for use in restaurants or elsewhere to establish acurrent of air and drive away flies. Electromotor fans are commonlyconstructed to be mounted on brackets or other supports, the blades orwings of the fan being commonly revolved on a horizontal axis. Such fansare stationary, being mounted once for all in a given place.

My invention provides an improved construction of electric fan which canbe connected with any incandescent-lighting system and which isportable, so that it may be placed on a table or desk and may be easilydisconnected and carried to another position. According to my inventionI construct the fan with a base, in which the motor is arranged, andwith a vertical shaft driven by the motor standing above the base to anydesired height and carrying the blades of the fan. The shaft is madetubular and through it passes a stationary bar or post, on the top ofwhich is fixed an electric-lamp socket or other equivalent means forconnecting electric wires, and from the terminals in this socket twowires extend down through the post, which is made tubular for thepurpose, and pass from the lower end thereof to the terminal connectionsThe fan being placed on a table or elsewhere in any convenient ordesired position,it is connected with a source of elec tric energy bymeans of a suitable cable provided with blocks or terminals, that at oneend fitting the socket at the top of the fan and that at the other endadapted to enter any ordinary incandescent-lamp socket. The fan isproportioned to be driven by a current sufficiently approximating thatwhich is used to feed an ordinary incandescent lamp, so that when thusconnected in a lamp-circuitit does not affect the operation of the lampsburning on said circuit.

Figure 1 of the accompanying drawings is an elevation on a small scale,showing my electric fan and the means for connecting it to thelamp-socket of an electrolier. Fig. 2 is a vertical transverse sectionthrough the base of the fan. Fig. 3 is ahorizontal section thereof onthe line 3 3 in Fig. 2. Figs. 4 and 5are respectively a fragmentary side elevation and plan showing the details of the device for attaching thefans or wings to the shaft of the electric fan. Fig. 6 is a fragmentaryelevation of a modified construction of fan, the lower part being partlyin vertical section. Fig. 7 is a horizontal section thereof on the line7 '7in Fig. 6.

Referring to the drawings, let A designate the base or mechanism case 5B, a fixed tubular handle mounted on the top thereof and projectingvertically upward; C, the revolving tubular shaft passing out from themechanism case through the hollow handle 13, and D the fan, consistingof wings or blades (1 d, having stems e e.

The mechanism case A consists of a shell or casing a, fastened beneathto a base plate or block b, which may be of wood. \Vithin this mechanismcase is an electromotor, designated as a whole by theletter M. Thismotor is constructed with a fixed frame E, part of which serves as thefield-magnet of the motor. The base-plate c of this frame, which isfastened down securely to the base-block I), is formed with a centralboss, in which is firmly secured or otherwise fastened the lower end ofa stationary vertical post F, which passes up through the tubular shaft0 and projects from the top thereof above the fan, as shown in Fig. 1.This post is made tubular in order that the wires w w, leading to themotor, may be carried down through it, as clearly shown in Fig. 2. Thesewires terminate at the top in a lamp-socket or other suitable terminalconnection G. (Shown best in Fig. 6.) The tubular shaft revolves aroundand is steadied and supported by stationary post F. The armature M ofthe motor is connected to this shaft in such manner as to rotate theshaft by its rotation. It may either be fixed directly on the tubularshaft, as shown in Figs. 2 and 3, or it may be mounted on a separatearmature-shaft and connected to the tubular shaft 0 by gearing, as shownin Figs. 6 and 7, the former construction being preferable, except whenit is desired that the armature shall revolve at a higher speed than thefan, in

which case the construction shown in Figs. 6 and 7 will be preferred,wherein a small pinion f is fixed on the armature-shaft and gears with alarger gear 9, fixed on the shaft 0. In either construction the armaturemay be Wound as a Granime ring or Siemens drum, or any other type knownto electromotors, and the construction of the field-magnet andcommutator of the motormaybe such as used with any of the numerous knowntypes of motors, or may be varied to suit any special requirements, itsparticular construction being immaterial to my invention. The lower endof the tubular shaft 0 is provided with a stepped bearing in thebase-frame c, and to render this bearing as frictionless as possibleballs h are inserted in agroove formed in the boss, as clearly shown inFig. 2.

My improved electric fan is designed to be connected to any electricalfixture or electrolier in place of an incandescent lamp.

In Fig. 1, H designates a combined gas-fixture and electrolier havingthe usual incandescent-lamp socket G for the insertion of an electriclamp. To connect my fan, this lamp is removed from the socket and a plugor terminal 2'. at one end of a conducting-cable I is introduced intothe socket G in place of the lamp. The corresponding plug at the otherend of the cable I is inserted in a socket G in the top of the post F.Upon turning on the current it passes through the wires in the cable Iand through the wires 10 within the tubular post F to the electromotor Min the base, in the manner clearly shown in Fig. 2. A fan thus connectedmay be lifted by its handle B and moved from one table or place toanother within the limit of the length of the cable I. In order toprovide sufficient slack for this purpose, the cable is looped somewhatin the manner shown in Fig.1, and has applied to it a springj to hold upthe loop or slack and prevent the cable from falling into the way of therevolving wings (Z d of the fan. As the electric fan is moved fartherfrom the electrolier, from which it draws its current, the cable I isstraightened out, distending the springj. The cable I might be made ofspring-wire to the same effect.

The separate fans or wings d d are attached to the shaft 0 in suchmanner that they may be raised or lowered on the shaft to differentheights, and so that the wings maybe turned to different angles andmoved out or in to different radial positions. For this purpose I employclamps, fastening their stems e e to a disk 70, which is fastened on theshaft 0 by a setscrew so that it may move to different heights. Fig. 6shows a clamp consisting of a spring-arm Z, mounted over the disk 7t,and pressed down by a thumb-screw m to engage the end of the stem orhandle of one of the fans d. I prefer, however, the construction shownin Figs. 4 and 5, wherein two clamps Z Z, consisting each of a yokebridging across between the two stems, which are laid parallel, as inFig. 5, and pressed down each by a thumb-screw m, as shown. Beneath eachclamp is a small spring a, which acts to raise it when the screw isrelaxed, so as to permit of the easy removal or adjustment of the stems.

My improved electric fan has the advantages of portability, beingreadily removable from table to table in a restaurant or elsewhere, andits electric connections are made in such manner as to avoid carryingthem through or against the table, so that the movement of the fan fromone position to another does not interfere with its connections. Bycarrying the connecting-wires down through the standard or post withinthe revolving shaft I avoid all bottom connections, and consequentlyavoid carrying electric wires into close contact with a table or desk,where their presence would be objectionable. The conducting-wire isarranged entirely overhead, where it is wholly out of the way and whereit admits of moving the fan from one position to another.

My improved fan has also the great advantage that it may be connectedwherever incandescent lamps are used without the running of specialwires or circuits. For this purpose the connecting-cable I will be madeof different lengths to adapt the fan for different positions, accordingto the distance that is desired to be operated from the lamp-socket withwhich it is to be connected.

My improved electric fan maybe modified in many ways in matters ofdetail, in the construction of the motor, and in the generalconstruction and arrangement of the working parts of the fan, andparticularly in the means for connecting it with a source of electrice11- ergy, without thereby departing from those features which areessential to my invention.

I claim as my invention the following-defined novel features orcombinations, substantially as hereinbefore specified, namely:
